Abstract
Abstract A device for dropping individual rolled flat bars moved crosswise in a stack over an inclined rake-type cooling bed on an adjacent horizontal roll-type cooling bed comprises inclined transport rolls having crescent-shaped bar stops with a maximum height corresponding to the top of the bar stack and rotatable to decrease the crescent level for dropping the bars successively on the roll-type cooling bed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
118 words
Device for dropping individual flat bars moving in a stack crosswise over a rake-type cooling bed on an adjacent roll-type cooling bed, the improvement comprising inclined support rolls (4) for receiving stacked flat bars (3) against bar stops (9) presenting a crescent-shaped abutment face (9a) rising from the periphery 4a of the support rolls 1, said abutment face having a maximum elevation above the support roll periphery corresponding to the height of a stack of flat bars (3), said support rolls (4) with their bar stops (9) being rotatably mounted for movement beyond the arcuate extent of the crescent-shaped abutment face (9a) and their roll axes being inclined beyond the friction angle of the stacked superimposed flat bars.
